SPECIFICATION formingpart of Letters Patent N o. 727,032, dated May 5,19'03.

Application filed August 16, 1902.

To ctZZ whom, it may concern,.-

Be it known that I, NELSON J. TUBBS, a citizen of the United States, anda resident of Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in Churns,of which the following is a specification.

The primary object of this invention is to provide a churn which shallbe simple in construction and effective in operation and in which theoperating mechanism for the churndasher and the supporting-legs for thechurnbody can be readily and conveniently taken apart and stowedV withinthe churn-body for convenience in shipping the churn and to reduce the.apparatus-to a compact form for storage.

With the above objects in view the invention consists in the particularconstruction and arrangement of parts and their combination, all as willbe hereinafter fully described in the following speciication and morespecifically set forth in the appended claims.

In the drawings which form a part of this specification, Figure l is avertical sectional view of a churn constructed in accordance with myinvention. Fig. 2 is a sectional view showing the connection between thedasherrod and the supporting-frame for the operating mechanism. Fig. 3is a detail view of the lower dasher. Fig. 4 is a detail view of thesupporting-bracket for the standard.

Referring to said drawings, A designates the churn'- body, which ispreferably cylindrical in shape and is constructed of wood in order thatthe fixtures hereinafter described may be secured thereto by ordinarywoodscrews; but, if desired, the said churn-body may be made ofmetal andthe fixtures riveted thereto. This churn-body is supported directly uponshort'legs B, the upper ends of said legs tting into sockets b, securedto the lower end of the churn-body, and the socketopenings are disposedat an angle, so that the supporting-legs will spread, as shown. Byproviding the sockets and connecting the supporting-legs directlythereto the said legs may be readily removed and stored within thechurn-body.

Secured upon one side of the churn-body serial No. 119,943. (No noaa.)

A, near the upper end thereof, is a casting C, provided with a verticalopening which is adapted to' receive the lower end of the standard D ofthe frame which supports the operating mechanism of the churn. The saidcasting is provided with a set-screw c, so that the supporting-frame canbe readily adjusted to any desiredl height and securely held. Thesupporting-'frame consists of the standard D, a horizontal arm d, andvertical members d d2, extending upwardly from said arm at the portedbythe frame in the manner hereinafter described.

Mounted upon the shaft E and bearing against the outer side of theshaft-bearing d' is a large bevel gear-wheel F, inl mesh with a pinion Ion the hollow dasher-rod L, which is adapted to revolve within thechurn-body and carries the dashers hereinafter particularly described.The upper end of the dasherrod is supported in a socket M, having abifurcated upper end, which receives a fiat projection n 011 a sleeve N,loosely mountedon the inner end of the driving-shaft E, the said sleevebearing at one end againstrv the gear- Wheel F and at the other endagainstawasher o, held on the shaft by a Cotter-pin o'.' It'will be herenoted that the flat portion n does not project from the center of thecollar N, but is located nearer onez end `thereof than the other, thisbeing provided for to locate the socket M at different distances fromthe gearwheel F, so that different-size piuions may be mounted on thedasher-rod to mesh with said gear-wheel. To this end the said pinion Iis removably mounted on the dasher-rod, being secured thereon by aset-screw fi. It

will also be noted that the socket M is pivotally connected to theprojection n of the A l 4 I.'

sleeve N by the Cotter-pin m, which passes' ,through them, and that thisprovides a Vyielding joint that will obviate any strain yon the parts. V

The hollow dasher-rod is threaded at its lower end to receive the dasherP, which is screwed thereon, the said dasher being provided centrallywith a conical bearing'p, which is stepped in a hard-wood socket Q,located in the center of the bottom of the churn. This socket Q isdriven in a hole formed in the center of the bottom of the churn andwhen Worn can be readily replaced byanother. ThedasherPconsistsofasquareplate having centrally a threaded hub 1f, by which it is screwed uponthe lower end of the dasher-rod, the lower end of said hub forming theconical bearing hereinbefore referred to. Extending across the underside of the plate or dasher P from the lower end of the hub p' arehollow ribs p2, the dasherrod terminating above said ribs, so that airmay pass from said dasher-rod into said ribs, the latter opening out atthe outer end of the plate or dasher, so that when the dasher isrevolved rapidly the air will be drawn down4 the dasher-rod anddischarged from the hollow ribs by centrifugal force. The dasherP isprovided on its upper side with a number of vertically-projectingpaddles p3 of difterent lengths and disposed irregularly, as shown, theshort paddles at the inner part of the dasher being formed integral withthe hub p'. The particular arrangement of the paddles on the upper sideof the plate and the arrangement of the hollow ribs of the under sidethereof provides a suction which will draw the air down the hollowdasher-rod and discharge it into the body of milk or. cream, so as tothoroughly aerate the same, the air entering the upper end of thedasherrod through the opening at the upper end of the socket M.

Above the dasher P is located a dasher R, having inclined bladesprojecting from a hub, and in order that a dasher of this character maybe made more effective in operation I provide the blades with openingsfr. These openings serve to form additional currents,

and consequently agitato the cream to a greater extent than a solidblade.'

At opposite sides of the body of the churn are arranged vertical platesor breakers S, the lower ends of which are provided with points or pinss, which enter the bottom of the churn, while the upper ends areprovided with holes which register with holes in the sides of the churnand receive cotter-pins s', by which the said breakers are held inplace. The inner edge of these breakers are cut away, as shown, to forma vertical opening adjoining the sides of the churn.

The operation of the churn will be readily understood, and in practicaluse I have found that a revolving dasher-rod provided with dashersconstructed as herein shown and described produces a churn in which thechurning of the milk and cream is greatly facilitated. The changeablegear is provided so that a more rapid motion maybe imparted to thedasher-rod in churning sweet cream and milk, while a slower speed may beprovided for in churning sour cream 'and milk, it being understood thatone required afaster motion than the other.

By constructing the different parts of the churn as herein shown anddescribed the legs can be removed and placed in the churnbody and theparts of the operating mechanism all separated and placed in thechurnbody also. It will also be observed that the churn-body or barrelis firmly supported at the required height and that the frame whichsupports the driving mechanism is connected to the upper part ot' thebarrel, whereby the construction of the churn is considerably cheapened.Y

Having thus described my invention, I claiml. In a churn, thecombination with the barrel and vertical dasher-rod,of a socket securedto the upper end of the barrel, a frame having a standard secured insaid socket and providing bearings for a horizontal shaft, a gear- Wheelon the inner end of said shaft in mesh with a pinion on the dasher-rod,a sleeve on the shaft having a depending fiat portion, and a sockethaving a bifurcated upper end pivotally connected to the projectingportion of the sleeve, substantially as shown and described.

2. In a churn, the combination with the barrel and dasher-rod, of ahorizontal drivingshaft supported in a suitable frame and carrying agear-wheel in mesh with a pinion on the dasherrod, a sleeve on the endof the drive-shaft having a projecting portion, and a socket pivotallyconnected to said depending portion of the sleeve, the said socketreceiving the upper end ofthe dasher-rod, substantially as shown anddescribed.

3. In a churn,the combination with the barrel and flasher-rod, of asupporting-frame providing vertical bearings, a drive-shaft mounted insaid bearings, a crank-handle adjustably secured to the shaft on oneside of a bearing, and a collar adjustably secured to the shaft on theother side of said bearing; together with a sleeve having a projectingportion nearer one end thanv the other, a socket pivotally connected tosaid projecting portion, a removable pinion on the dasherrod, and agear-wheel on the drive-shaft adapted to mesh with the pinion,substantially as shown and for the purpose set forth.

4. In a churn, the combination with the barrel and dasher-rod, ofsockets secured to the lower end of the barrel and to one side of theupper end thereof, supporting-legs adapted to engage the lower sockets,and a supporting-frame for the driving mechanism removably connected'tothe upper socket; together with the drive-shaft supported in the frame,a sleeve on the inner end of the shaft, and a ICC IIC

socket pivotally connected to said sleeve, the said socket receiving theupper end of the dasher-rod, substantially as shown and described.

5. Ina churn, the combination with the barrel and hollow dasher-rod, ofa dasher mounted on the lower end of the dasher-rod and consisting of aplate having a hollow hub in which the dasher-rod is stepped, a seriesof vertical plates or paddles arranged around the hub, a series ofvertical plates or paddles at the outer ends of the plate, and anintermediate series of vertical plates or paddles, the latter beingdisposed out of line with the others to leave spaces between the saidplates or paddles; together with hollow ribs or tubes extending acrossthe under side of the plate from the hollow hub.

6. In a churn, the combination with the hollow dasher-rod of adasherconsisting of a across the under side of the plate, said ribscommunicating with the hollow dasher-rod, substantially as shown anddescribed.

In testimony whereof I affix my signature in the presence of twowitnesses.
